XTX50 NITROX regulator

The APEKS XTX50 Nitrox is a dedicated scuba regulator for use with oxygen-rich mixtures, suitable for up to 100% O₂. Apeks Nitrox regulators are colour coded for quick identification and are specially cleaned and assembled in a Class 'J' (10,000) cleanroom, using oxygen-safe components and lubricants. Available in Yoke ('A' clamp) or DIN connection, this scuba regulator combines O₂ safety with the proven performance of the XTX50. The Over-Balanced Diaphragm design provides superior performance at depth, while the Environmental Dry system prevents water ingress and contamination of the mainspring chamber.
